AUTOMATIC BUTTER-DISPENSING APPARATUS.

Specification of Letters Patent.-

Application filed September 5, 1912. Serial No. 718,785

T 0 all'whom it may concern Be it known that I, EDWIN M. LARSON, acitizen of the United States, residing at Los Angeles, in the county ofLos Angeles and State of California, have invented a new and usefulAutomatic Butter-Dispensing Apparatus, of which the following is aspecification.

This invention relates more particularly to a sanitary machine by meansof which chips of butter such as are used in restaurants and hotels maybe automatically cut from bars and ejected into butter plates therebyeliminating the necessity heretofore of handling the butter chips byhand during the preparation of the same for table use.

An object of this invention is to provide a machine to be operated bywaiters or other attendants in restaurants, hotels or other eati ngplaces whereby chips of butter will be dispensed individually andautomatically and without handling, so that the waiter or otherattendant by placing the individual butter dish in position to receivethe chip and then operating the machine will deliver a butter chip ofthe appropriate size onto the butter plate so that it may be takendirectly from the bar of butter to the guest or customer in perfectsanitary condition.

An object of this invention is to provide a novel unitary machine whichwillv automatically guide a body of material such as a bar of butterinto positlon, cut rectangular parallel sided chips from such body andeject'the out portions into plates.

I regard this invention as pioneer, being the first machine which may becharged with one or more bars of butter and then when operated will atevery operation without further attention, out a chip of butter andeject the same into the receiving butter plate so long as the charge isnot exhausted.

Further objects of this invention are simplicity, compactness, ease andconvenience of charging, large capacity, convenient and properrefrigeration, and invariable appropriate performance of the necessaryoperations at the proper times.

It is necessary that thebutter shall be kept at a proper temperature, sothat it will out properly without breaking or mashing and provision ismade whereby such temperature 1S readily maintained.

Other objects and advantages of thisinvention may appearfrom thesubjoined de-' tail description. if I Variouschanges of construction maybe made without departing from the invention or some of the'featuresthereof. v 7

Referring to the drawings, the invention comprises a combination ofmechanisms which will be considered in the following order: mechanism A,for cutting the loutter; mechanism B, for automatically stopping thecutter centrally between the cutting strokes; mechanism C,'for ejectingthe butter chips; mechanism D, for connecting the cutter and ejectoractuating mechanism with the butter bar advancing mechanism; mechanismE, for advancing the butter bar; mechanism F, for supporting the butterbars and moving them successively into position for cooperation with thebutter bar advancing mechanism; and mechanism G, for regulating thethickness of the butter chips.

. This invention includes said mechanisms and the said combination andalso various parts and combinations of parts that will be more fully setforth in tail description.

The apparatus shown is designed to be actuated by the oscillations of anoperatingleft at the Provision is also handle, which moves right andfront of the machine. made for automatically dropping the butter barsupporting tray after the same is emptied and provision is also madewhereby access to the interior of the case may be had conveniently fromthe front to remove the empty trays and to reach the internal mechanism.

- The accompanying drawings illustrate the invention, Figure 1 being ona reduced scale and the other figures-on a larger scale.

In this view the parts are adjusted. tocut butter chips twice as thick as those out by the machine in theprevious views. Parts are in the position they assume when the plungerhas just been released and is about to retract to the position shown inFig. 15. The guard is omitted. Fig, 18 is a fragmental broken elevationviewed from itregular line .90 Fig. 17 and is analogous to the rightfragmental portion of Fig. 8. Parts are shown adjusted to secure greaterbetween the panels 3 on a vertical axis; the

intermediate section or member 5 being hinged on a horizontal axis atits lower edge and capable of being swung down and out to permit easyaccess tothe interior, and being provided with a guard 6 detachablymounted above and in front. of a central front opening 7 therethroughwhich com municates with the interior of the case for the ejection ofthe butter chips.

Inside the case there is provided a space for an ice chest 8 having legs9 to hold a supply of ice in the upper rear portion of the case to coolthe case and its contents, including the charge of material to bechipped and dispensed and also the mechanism hereinafter described forsupporting moving, holding and cutting said material, as the butter bars10 andlO, The bottom of the ice chest 8 is provided with holes a, (seeFigs. 14-, and 17,) through which water from the melting ice may dripinto a bifurcated pan 11 that rests upon the floor 12; said pan beingprovided with a faucet 13 preferably at the front of the machine todrain the pan as the ice melts. The pan is bifurcated so as to fit intothe case at the rear and on both sides of the mechanismcarrying framewhich will be hereinafter fully described.

The guard 6 is in the form of a hood fitting over the opening throughwhich the chips are to be ejected and extending below said opening andopen at the bottom only considerably below the bottom of the, saidopening through which the chips are to be ejected, so that the cold airwill be conserved in the machine.

Butter-cutting mechanism A.The butter bars 10. 10 are carried by the barholders comprising trays 10 supported by suitable means hereinafterdescribed and adapted to successively hold their respective bars incutting position behind the central opening 7 through which the chipsareto be ejected.

The butter-cutting mechanism A is carried by the hinged intermediatesection 5 and comprises a horizontal transverse slide 14 having anorifice 15 therethrough "and mounted to reciprocate transversely of themachine in top and bottom guides 16 carried by and forming part of theintermediate which is hinged at the bottom on.

section 0 a horizontal axis 17 and is held normally up-- right in closedposition by the latch 18 engaging a portion of the frame 1 at the frontof the case. On the inner face of said slide is mounted the cuttermeans, preferably in the form of an individual filose cutter 19, beingpreferably a single wire, extending vertically across the open space 15of the slide 14; and being detachably secured inplace by suitable meanssuch as studs 20 fixed to the slide above and below the orifice 15, saidwire being passed through holes 21, adjacent the edges of the orificeand wrapped around said studs and'stretched taut and clamped against theslide by nuts 22 screwed home upon the studs to firmly hold the wire. i

The'transverse slide 14% is provided at one side with a vertical slot 23transverse the slide, through which slot extends the pin 24 of a} crankarm 25 that is between theintermediate member and the slide and is fixedupon one end of a stub shaft 26 which extends through and is journaledto the intermediate member 5 and is operatable'a half turn at a time'bya crank lever 39 outside the case. The crank pin it fits the slot whichis in parallelism with the. filose cutter and is equal in length to thediameter of the path of the crank pin so that a complete cycle of theslide is effected at each full revolution of the pin.

By openingthe intermediate section 5 the butter-cutting mechanism may bedropped down out of the way as indicated in dot and dash lines in Fig. 7thus giving free access to the interior of the case from side to sideacross its front. 7

The slide 14: is arranged to normally stand at rest'with the filosecutter in a vertical plane centrally of the opening 7 so that vwheneverthe butter bar is moved forward while the slide is in its normalposition of rest the bar will be slit along its vertical mid-plane bythefilose cutter. The mechanism which operates the slide is constructedand arranged as hereinafter described to alternately'move the slide fromits central position of rest to one side and back to rest and then viceversa, from the point of rest to the other side and back to rest; thatis to say, the filose cutter normally stands at rest stationar filosecutter 19 at thealternate' restings of the cutter, so that at eachadVance of the bar a longitudinalslit 27 will be cut in the bar along theverticaliaxial plane of the bar, so that the portion 28 projectingforwardly from the holder will be cut off from. the bar in the form. oftwo chips that are severed at separate strokes independentlv of eachother by reason of the alternate movements of the cutter from rest tothe sides in first one and then the other direction one movement of thecutter forming the chip in Figs. 7 and i l and the other movementforming the chip 30 in Fig. 4.

Ivlounted upon the front of the hinged intermediate section at each sideof the opening 7 are slotted slides 31 provided with abutments adaptedto extend into said opening 7 in position to support the sides of theforwardly projecting portion of the butter bar thereby affordinggripping means to hold the forwardly proportion 28 of the butter baragainst (llSplflCQHlQlltunder pressure of the filose cutter 19. Theabut-ments 32 are adjustably secured in place upon the member 5 by meansof screws 33 extendin through slots in said abutments and screwing intosaid member The filose cutter is adjacent to the abutments beingfastened just far enor h ba k to be out of alinement with the edges ofthe same.

The stub shaft 26 (see Figs. 1% and 1 to 5) is fixed by pin at its innerend to the crank and is mounted in a bearing 35 ixed to and projectingfrom the front of he hinged member 5; and upon the outer end of saidshaft there is secured by pin 26 a collar 36 provided with twooppositelyarranged ratchet teeth 37 adapted to be alternately engaged bya spring-controlled pawl 38 carried by the operating crank lever thathand operated in the direction of the solid curved arrows in Figs. 3 andand is returned, in the direction of the broken curved arrow in saidFig. 3, by a spring 40 that is fixed at one end to the hinged sectionand is coiled around the bearing inside the housing or crank drum .1 andsecured at the other end to the crank lever 39 (see the dottedconstruction in Fig. 2) to return it to rest position against a stop 1 6whenever the crank lever is released after being operated to turn thecrank 25 to move the slide in either direction. The ratchet roller 12 inthe pocket 43 prevents backwarc rotation of the shaft 26 and crank Thebars to be cut are twice as wide as they are thick and to cut them intosquares of any desired thickness it is only necessary to move the filosecutter from and to its central station alternately right and left eachstroke from and return to rest serving to sever a chip of a thicknessdetermined by the depth to which the cutter enters the bar when the baris advanced.

Mechanism B.-The mechanism B for au arm at the end of the return strokeof v the operating cranklever 39 as said lever returns to normal uprightposition against .the I stop pin 46 as shown in Fig. 1; the rock: shaft4'? to which said arm is fixed being journaled in the member 5 andoperatively connected inside said member with two 0scillating bars 4:3,e9, that are connected together by a connecting rod 50, moves said barssimultaneously in reverse directions; the

bar being fixed near one end to the rock shaft f? and provided with astop face 51 at the end of its long arm, and pivoted at the short arm bya pivot 52 to the connecting rod 50, while the lower oscillating bar 1-9is provided with a stop face 53 almost vertically below the stop fa e 51and facing in the direction opposite thereto. lhe pin connecting the rodto the lower bar e9 is between the stop. face 53 and the pin whichpivots said lower bar tothe inter.-

mediate section and the pins 52 and 5d are equidistant from the centerson which said bars oscillate, while the faces 51 and 53 are practicallyequidistant from such centers, so tl at when the rock shaft 17 isoperated the stop faces are moved up: and down practically the samedistancethough in reverse directions.

T he weight of the rock shaft arm 4:5 and oscillating bar e3overbalances that of the oscillating arm l9 and connecting rod 50,. sothat when the rock shaft arm s5 is unsupported. by the cam the stop face53' is raised into the way of the pin 24- in its movement from right toleft in Fig. 1 and the stop face 51 is lowered into the path of said pinas it moves from left to, right. Consequently by this means when theoperating crank lever 39 is fully depressed to the dash line positionshown in Fig. 3 the pin 24. engages the lower stop face 53, thusstopping the operating crank lever 39 which is thereupon returned by thespring 40V to. the stop 46 at which point the rock shaft arm is againlifted by the cam at, so that at the next right movement of theoperating crank lever: the crank pin 2% is allowed to move onward; and.as it moves, the cam H is again withdrawn from the rock shaft arm 45whereupon the weight of the overbalancing parts drops the stop face51into the way of the crank pin 24: which is there. by stopped when thecrank pin reaches the position vertically above that at which it wasstopped by the face 53. It is thus seen that at each full right movementand d epression of the operating crank lever, the slide is moved tocarry the filose cutter from mid-position to one side and return to.midposition; the normal stoppage of the slide and the cutter it carriesalways occurring at the mid-position. i

t is to be noted that the means for relatively moving the cutter and thebutter bar are so constructed as to constitute, in each instance, meansto cause relative direct, nonpivotal movement between the cutter and thebutter bar, thus to form the usual butter chips having parallel fiatsides.

Mechanism C.The mechanism C for ejecting the butter chips is illustratedin Figs. 1,2, 3, l, 5, 7, 15, 16 and 17. The ejector comprises a sleeve56 having an actuating pin and ejecting finger 66 that is slidably androtatively mounted between stops57, 58 upon a guide-rod 59' that iscarried by the intermediate section 5 and that extends parallel with andadjacent tothe slide l l; said guide-rod being preferably mounted insaid stops which are fixed to the front of the hinged intermediate frontsection 5. Ejector actuating tappets 60, 61

provided with downwardly diverging faces 62, 62 and horizontal slots 63are fixed to the slide by screws ea passing through" said slots and,when the screws are loosened, are adjustable toward and from each otheralong the slides. The actuating pin 65 extends between the faces 62, 62,and a spring 67 in the form of a spiral loop is bent around the ejectorsleeve, one loop end of the spring being under the actuating pin 65andthe other loop end resting against the slide 14, so that the upwardpressure of the spring on the pin retracts the ejecting finger. Saidspring yieldingly holds the vertical tip 68 of the ejecting linger in avertical transverse plane that extends just in front of the filosecutter. As the slide 14 moves to the right the tappet face 62 engagesthe actuating pin 65 and slides the ejector along the rod 59 until theend of the ejector sleeve 56 impinges against the block 58, whichthereupon holds the ejector against further lateral movement while theoblique tappet face 62 continues to move to the right thereby forcingthe actuating pin down and overcoming the resistance of the spring 69and throwing the ejecting finger and the tip 68 forward. The result ofthis operation is that the ejecting tip 68 runs along the top of therear side of the butter chip just in front of the filose cutter untilsaid chip is severed and then said tip moves outward to eject the chip.On the return movement of the sleeve toward the left the ejector slideremains momentarily stationary on the guide-rod 59, while the filosecutter passes the ejector tip. When the tappet face 62 has receded fromthe actuating finger the spring 69 returns the ejector tip to itsretracted position, and then the tappet face 62 engages said pin andslides the ejector along the guide rod behind the filose cutter; andupon the next actuation of theslide the thus directing the chipforwardly toward' the butter plate 70 which is placed centrally underthe guard 6 upon an extension of the floor 71 that forms the butterplate shelf. 7

The timing of the ejecting mechanism with relation to the cuttingmechanism may be accomplished by the adjustment of the slotted tappetstransversely along the slide .14 upon their screws 6a.

Mechanisms D, E, F andGr are mounted inside the case upon the frame 72that is fixed to the floor and to the front portion of the frame of thecase by screws 72, and that comprises two front and two rear standards73, 74c and top and bottom braces 75. i i

211' echam'sm D.Th e mechanism D for connecting the cutter and ejectoractuating mechanism with thebutter bar advancing mechanism comprises arigid rock-shaft arm 76, arranged in operable relation to the crank-pin2i, and mounted on a rock-shaft 77 that is journaled to the front andrear standards 73, 74: and that isconnected by an arm 78 and aconnecting rod 79 with one end ofa pivoted lever 80 that is pivotallymounted at 81 upon the rear extension 82 of the frame 72; the other endof said lever 80 being connected by a connecting rod 83 with a ratchetarm 84c that is journaled on a transverse driving shaft 85 and isprovided with a spring-pressed driving pawl 86 which engages a ratchetwheel 87 fixed on said shaft to turn the shaft the space of one or morenotches of the'ratchet wheel at each complete revolution of thecrank-pin 2 The spring-pressed locking pawl 88 pivoted at 89, underneaththe ratchet-wheel 87, to the extension 82 prevents back movement oftheratchet wheel.

As the rockshaft arm 76 is operated by the crank-pin 2a the pawl 86 isretracted from the ratchet wheel, and in order to drive the pawl 86 andthe butter bar advancing To this end lost motion connecting means areprovided whereby the spring 90 may be compressed at a determined periodas the crank-pin 2i actuates the rock-shaft arm '1' 6, and whichconnecting means under the action of the spring will suddenly actuatethe pawl 86. Said means comprise the driving lever 91 fulcrumed at 92 tothe framevextension below the lever 80 and provided with a roller 93between the fulcrum 92 and the point at the end of the lever 91 on whichthe spiral spring 90 acts through the knifeedge bearing '93; said springbeing held in place by a spring holder formed by a rod 9-1 run throughthe bearing and the spring, and a tension nut 95 on said holder.

It will be seen by reference to Figs. 7 and 8 that on the upstroke ofthe connecting rod 7 9, the pawl 86 is retracted and as the roller 93 isacted on by the lever 80 the free end of the lever 91 arid the washer 93are raised thereby compressing the spring 90; and that as soon as thecrank-pin 2%. has passed the rock shaft arm 76 the spring 90 at onceacts to operate the lever 91 and the pawl is thereby advanced to drivethe ratchet wheel and rotate the driving shaft.

The lower portion of the spring holder 9% is curved in an are describedfrom the fulcrum 92 of the lever 91 so that the end of said lever mayrun freely up and down said guide to compress the actuating spring andto respond thereto.

The driving shaft is connected to drive the mechanism hlfor advancingthe butter bar.

Mechanism E.The mechanism E for advancing the butter bar comprises amutilated gear 96 fixed to theshaft 85 and engaging a rack 97 fixed. tothe plunger '98 having the adjustable butter "advancing plates '99, 99mounted at the forward end. thereof and separated by 'a narrow openspace forming a cutter-way 100 to allow the plates to pass one stepbeyond the filose cutter after the last chips have been scraped from theplates and ejected from the machine. The toothed segment 101 of themutilated gear 96 is of suilicient length to move the slide forward itsfull length at each revolution of the inntilated gear to carry the'baradvancing plates one step beyond the filose cutter; and the blanksegment 102 of said gear 96 is of suflicient length to disengage therack and allow it to run freely back at the end of each revolution ofthe gear.

The butter moving plunger 93 is mounted in a horizontal guideway 103provided with a standard 104v to support the rear end of the plungerretracting spiral spring 105, the front end of which is connected by astandard 106 with the slide.

The locking. pawl 88 is constantly in position to prevent back movementof the ratchet wheel driving shaft 85 and the mutilated gear '96; and itis necessary that the Inntilated gear shall not be allowed to revolveforward during the retractionof the bar advancing rack 97. 'With thisend in view a latch 107 is pivoted to the frame extension S2-and isoperated by a spring 108 to engage a catch in the form of a pin 109 thatprojects from the mutilated gear in position to engage the latchshoulder 110 when the blank segment 102 of the mutilated gear isadjacent to the rack 97, so that at that time the mutilated gear is heldfrom back action by the ioc'king pawl 88 and from forward when by thelatch 10?.

A tripper in the form oi a pin 111 fixed to the rack, projects into theway of the latch 107 to retract said latch from the catch pin when therack is fully retracted. A rack starter in the form of a finger 112fixed to and revolving with the mutilatedge'ar extends to engage thestarting shoulder 113 on the rack, when the tripper has released thelatch sothat on the next forward r movement of the pawl 86 the rack willbe advanced to engage the toothed segment 101. The machine is intendedto chip, in succession, a number of butter bars; and with the object ofallowing the siic'c'e'ssive bars to be fed vertically, pro ision is madewhereby the butter-advancing plunger shall be supported wholly by 'meansoutside the space either above or below the butter bar carrier. Vltllthis object in view the slide-way 114 of the frame extension is extendedrearwardly the full length of the plunger, and is slotted longitudinallywith parallel side slots 115 and an intermediate t'oo'thedslot 116. Onthe slide-way list is mounted an auxiliary slide 117 on which is mountedthe plunger slide 118 that carries the rack and is provided withparallel slide slots 119 and an intermediate toothed slot 120. The teeth121 of the intermediate slot 116 are on one side of their slot, andteeth 122 of the slot 120 are on the other side of their slot, and astub shaft 123 is journaled in the aiiXiliary slide 117 and is providedat its opposite ends with pinions-124, 125 to engage the teeth of theintermediate slots respectively, so that as the plunger slide isadvanced, the auxiliary slide is advanced at half the speed, and viceversa; thus opera-ting to keep the auxiliary slide on the guide tosupport the plunger slide when it is moved into the way of the butterbars. A

v Retaining blocks 126 are fitted to the auxiliary slide and run in theslots 115 in which they are dovetailed to hold the auxiliary slideinplace on the slide-way. "Other 'retaining blocks 127 are in likemanner fastened to the auxiliary slide and dove-tailed in the slots ofthe plunger "slide.

7 By this construction the plunger is capae 'ble of forward extensionthe full length of thebiitter bar and 'isyet firmly supported by therear extension oht'he frame which does not project into the way of thebutter bar or the carrier therefor. V

The guide bar 12? fixed to the rear frame extension extends over theedge of the plunger slide to hold it from drooping as it is shovedforward.

Mechanism F.The mechanism F for supporting the bars of butter and movingthem successively into position for cooperation with the butter baradvancing plunger comprises four bracket carrying sprocket chains 12Smounted in pairs on pairs of sprocket wheels 129, 129 on opposite sidesof the butter bar way 130. The brackets 131 on said chains are arrangedat intervals apart somewhat greater than the thickness of the butterbars to be chipped, and butterbar supporting trays are providedaccording to the number of superposed butter bars that can beaccommodated at one time in the butter way. The upper sprocket wheels129 are mounted on driving shafts 133 that are journaled to the frame 72and said shafts are connected by gearing 13%, 135, 136, 137 to rotate atthe same speed, said gearing being fixed to the frame 72. The lowersprocket wheels 12-9 on one side of the frame are fixed on a shaft 138that is journaled to said frame, and an escapement wheel 139 provided atintervals on one side with teeth 140 is fixed to the end of said shaft.An escapement lever 141 is pivoted at 142 to the bracket 113 on the rearframe extension and is normally held by the spring 144 in the way ofsaid teeth to support the escapement wheel against the weight upon thebrackets. The upper end of the escapement lever 141 is provided with a.front oblique face 1 15 extending into the way of a tappet 146 that ispivoted to the plunger slide and is held by a spring 145 against theforward stop M8 on said slide, so that when the plunger returns on itsbackward stroke the tappet will engage the escapement lever andmomentarily withdraw it from the tooth of the escapement wheel withwhich it is engaged and allow the load of the brackets to move thesprocket chain and wheels, thus lowering the empty tray out of the wayand the next tray above into position with the butter bar alined withthe plunger and central opening 7. The escapement lever is normally heldoblique to the plane of the escapement wheel, so that when its upperlimb is in position to intercept a tooth its lower limb is withdrawnfrom the way of the teeth; and said lever is arranged in a common planewith a lower chord of the escapenient wneel. The escapement teetharebevcled on their ascending faces to engage the underside of the lowerend of the lever should said lever fail to return to its normal positionby the action of the spring l fe after being withdrawn by the tappet 16, thereby to insure swinging the lever to move its upper end into theway of The teeth are spaced on the escapement wheel a distance apartsufiicient to allow the sprocket'chain to more the space between twobrackets, so that when the escapement lever is thrown off to release atooth, its upper limb is immediately returned at the close of thebackward stroke of the tappet by the spring 1 14 into the path of thenext tooth. Consequently, whenever the escapement lever is tripped byits tappet, the butter bars and their supporting trays are allowed todescend just far enough to bring the lower most butter bar into the wayof the plunger. I

The brackets are arranged on the sprocket chains in such positionrelativeto the operating parts that when the sprocket chain is stopped aset of brackets are in position to support the butter bar and tray on alevel with the filose cutter and the opening 7 through the intermediatehinged section of the case,'so that the butter bar will be supported inthe path of the plunger ready to be forced through said opening as theplungeris advanced step by step.

The butter bar holder 10 comprises a tray 149 formed of a plate havingears 150 bent up at its rear end to hold the rear end of the bar. andprovided with butter bar guides 151 at the front end to direct the barinto thepath of the filose cutter. Said guides are adjustable beingprovided underneath the plate with arms 152 pivoted to the plate at 153,153 and provided at their ends to readily pass between the lipsMechanism G.The mechanism (z for regulating the thickness of the butterchips comprises means for changing the position of the rock shaft arm 76and for this purpose a movable bearing 155 is slidably mounted on one ofthe upright front standards 73 and is provided with a portion 156 toengage the under side of the arm 76. A pawl 15'? provided with a handle15? is pivoted to the bar and adapted to engage a shoulder formed on thestandard 73 to support the arm-engaging por ion lfifiin an elevatedposition to hold the arm 'TG'aslant at one angle. By withd awing the pawdown the standard until. caught by the supporting hook 155, therebyallowing the rock shaft arm 76 to drop to a different angle with thepath of the crank-pin 2a. When the rock shaft arm is supported in itsupper position the crank shaft escapes from the arm after moving the armthrough a limited arc, but when the rock shaft arm is un supported bysaid portion, the crank pin 2% will reach said earlier and move itthrough a greater arc. l he action of the driving pawl 88 isproportionately greater or less, depending on whether the rock shaft arm76 is supported at the lower or upper position.

In the machine illustrated there are fiftythree teeth in the drivingratchet wheel 87 so that when the rock shaft operates the driving pawl86 only one notch at a time, the bar will be cut into fifty-twotransverse slices of two chips each, and the fifty-third tooth willoperate to move the plunger forward one step beyond the position wherethe filose cutter was when the last chip was released This additionalstep is necessary in order to advance the plunger to a point where therack is free from the mutilated gear; and when this point is reached,the spiral retracting spring 105 immediately retracts the plunger; andthe escapement being released on the return of the plunger, the innerlimbs of the sprocket chains are allowed to descend, thus bringing a newbutter bar into position in front of the plunger and dropping the emptybutter bar tray to the floor of the machine from whence it may beremoved by opening the lower door 159 in the front of the machine.

When it is desired to increase the thickness of the butter chips thehearing 155 is lowered, so that the rock shaft arm 7:) will be movedtwice the arc in which it was pre viously moved; and when thus adjustedthe driving pawl is retracted two notches instead of one at eachoperation of the rock shaft and on its return by the spring 90 the lever91 will operate the driving pawl through the space occupied by tworatchet teeth, thus turning the mutilated gear twice as far as beforeandt-hereby advancing the plunger a like distance.

When the plunger has been advanced to the filose cutter it is desirablethat the next step which releases the plunger rack from the mutilatedgear shall only equal the space between the fifty-third tooth and theone immediately followin and to allow the ma chine to be fully adjustedto make the thicker chips, an adjustable runner 160 is pivoted to theratchet wheel 87 and clamped thereto by the slot and screw connection161, 162 see Fig. 17) so that by fixing the runner in place to close thespace between the first two teeth the pawl is supported against droppingtherebetween.

The operation of the apparatus will be understood. from the foregoing.The apparatus may be charged with butter bars by opening the front doorl and inserting the trays onto the brackets and placing the butter barson the trays. The butterbars may be stored in the ice ch ,st, the top ofthe case being removable for that purpose, and the o erator will use hisjudgment as to how many butter bars will be placed in the machine at atime, it being preferable to leave the butter bar and its tray in theice chest until the demand for it arises, but it is understood thatwhere the demand will be rapid, a larger number of trays with butterbars thereon will be placed on the brackets than when the demand isexpected to be limited. When the machine is thus charged, the plunger,being fully retracted, the waiterwill place a butter plate centrally onthe shelf 71 and will thenoperate the crank lever twice, thus bringingthe lilose cutter to a stop centrally in front of the butter bar andadvancing the butter bar at the close of the second movement toslit itby forcing its end past the filose cutter. At the next movement of thecrank l ver a chip will be cut and ejected onto the butter plate. If:two chips are desired, the crank will be operated again, thus depositinganother chip on the butter plate. At the end of this movement, theplunger is kicked forward by the actuating spring 90, As the work goeson the plunger is advanced after each second cutting until the last chipis ejected and the plunger rack has reached the open segment of themutilated gear, whereupon the retracting spring retracts the plunger andthe tripper 14:6 actuates the escaping lever thus releasing theescapeinent wheel and allowing the weight of the butter bars on thesprocket chains to more said sprocket chains, thus withdrawing the lowerbrackets from the empty tray and allowing such tray to drop to the floorand the next filled tray to go into position on a level with the filosecutter, after which the operation proceeds as hereinbefor described.

If it is found in case of very hard butter that the spring 90 does notact with sufficient force to drive the butter bar so as to cut it withthe filose cutter, the tension of said spring may be increased byscrewing down the tension nut 95, and vice versa; the nut will beloosened if the butter bar is softer.
